Best AI Song Generators in 2026: Suno v6, Udio and What Actually Ships a File

Suno retired every model it had ever shipped on September 9, 2026, moving its entire user base onto a new v6 lineup built with licensed catalog from Warner Music Group, BMG and Believe.

That is the second label-licensing shake-up to hit this category in less than a year. Udio settled its own copyright lawsuit with Universal Music Group on October 29, 2025, and traded user downloads for a bigger monthly credit allowance. Between the two deals, the AI song generator worth paying for in January is not automatically the one worth paying for now, because what moved is not sound quality.

It is which platform will actually hand you a file you can keep. For anyone choosing this week, that question decides more than any side-by-side listening test, and it is the question the rest of this guide is built around.

What Suno actually shipped this week

Warner Music Group settled its copyright lawsuit against Suno on November 25, 2025, the deal that unlocked label-licensed training in the first place. BMG and Believe signed their own agreements before v6 shipped, and Suno's own announcement names all three as partners in the new lineup.

Suno's own announcement page, captured 10 September 2026, the day after v6 shipped.

The announcement lists three new models: v6, built for polished, reliable output; v6-wild, tuned for stranger and more textured results; and v6-mini, a free-tier model available to everyone. v6 and v6-wild sit behind Suno's paid Pro and Premier tiers. The company says it will "retire our previous models and move Suno entirely onto the v6 generation" as the rollout completes, which means the v5.5 model that most 2026 reviews were written about is already on its way out, with no published per-account timetable for when every subscriber lands on v6.

The new models add partial editing by natural language, mashups pulled from multiple sources, sampling and beat isolation in one workflow, and prompts built from text, audio, images or video instead of text alone. Suno calls out one specific example in its own copy: generating from an emotional prompt like "feels like midnight on a rooftop" rather than a genre label.

None of that closes the gap that actually matters to a buyer. Suno has not published a per-stream payout for the artists whose catalog trained v6. Warner and BMG's compensation frameworks are, in the company's own words, "part of a plan for what comes next," not a live mechanic today.

What Udio traded away, and what it got in return

Udio's move looks different from Suno's, and it happened ten months earlier. According to Udio's own help center, downloading of audio, video and stems was disabled the moment the UMG deal closed on October 29, 2025, and has not returned as of this piece's publication.

Udio's own help center, captured 10 September 2026. The credit limits shown here match what this guide cites below.

In exchange, Udio bumped every subscriber's monthly credit ceiling. Standard rose from 1,200 to 2,400 credits a month, Pro from 4,800 to 6,000, and every existing subscriber received a one-time bonus of 1,000 non-expiring credits, according to Udio's own changelog for the partnership. Pro subscribers also gained the ability to run five concurrent song sets, up from four, for up to ten songs generated in parallel.

You can generate more music on Udio than you could a year ago. You just cannot take any of it with you. Udio has said publicly that it wants to reopen exports once its fully licensed platform launches, without committing to a date.

In practice, the "walled garden" description means a song lives in your Udio library, streamable from the app and shareable via an in-app link, indefinitely. What it cannot become is an MP3 on your laptop, a track in a video editor's timeline, or an upload to Spotify. For someone building a personal listening playlist inside Udio, that changes nothing. For someone who generated a jingle for a client's ad campaign, it is the whole ballgame.

The three questions that actually decide this

Skip the marketing copy and answer these first.

Do you need to download the finished file? If yes, Udio is out until its licensed platform reopens exports. Suno's paid tiers still allow downloads, capped by plan: 20 songs a month on Pro, 60 on Premier.

Do you need vocals, or an instrumental bed? Suno and Udio are both built around full songs with sung lyrics. If you need a 90-second commercial-use backing track with no voice, Stable Audio is a better fit than either.

What's your monthly volume? A podcaster who needs one intro theme a month has different math than a marketing team generating dozens of short-form video soundtracks a week. Credit ceilings, not sticker price, decide which tier actually covers you, and both Suno and Udio meter generations by credits rather than a flat song count.

Do you need commercial rights on day one? Every free tier in this category, without exception, restricts commercial use. Budget for a paid plan the moment a song leaves a personal project.

How much lock-in can you tolerate? Udio's model ties every generation to its own player, permanently, unless the company changes course. Suno's model ties you to a download cap instead, which is a softer form of the same problem: miss a month's 20-download allowance on Pro and the extra songs simply wait for the next billing cycle rather than disappearing. Neither is "no lock-in." They differ in what gets held back.

The shortlist

Suno's pricing page, captured 10 September 2026. Pro includes 2,500 credits and 20 downloads a month; Premier includes 10,000 credits and 60 downloads, the same caps this guide cites in USD (the page defaults to the visitor's local currency).

Tool · Best for · Price · The one caveat

Suno Pro · A downloadable, commercially usable song this week · $8/month, $6.40 annualized; 2,500 credits, 20 downloads a month · Free-tier songs cannot be downloaded or used commercially

Suno Premier · High-volume commercial output · $24/month, $19.20 annualized; 10,000 credits, 60 downloads, full Suno Studio · Same v6 lineup as Pro, just more headroom

Udio Standard · Composing inside a licensed catalog you won't export · Around $96 a year per Udio's own help center, roughly $8 a month · Downloads have been off since October 29, 2025

Stable Audio · An instrumental bed with a real commercial license · Roughly $10 to $12 a month depending on tier, per Stability AI's pricing page and independent trackers · No vocal-first workflow; tracks are capped around three minutes

Riffusion · Nothing. It no longer exists as a product. · N/A · riffusion.com now 301-redirects through producer.ai to flowmusic.app

That last row is worth sitting with. Several older "best AI song generator" roundups still list Riffusion as a live pick. It is not one. The domain forwards through an intermediate producer.ai redirect straight to flowmusic.app, a different branded product, with no Riffusion-branded landing page left standing anywhere in the chain.

Stable Audio is the odd entity out here, and worth a beat of its own. It comes from Stability AI, the same company behind the Stable Diffusion image models, and it is built for instrumental production rather than full songs with lyrics. Free-tier output stays non-commercial; Stable Audio's paid tier is where the commercial license and the roughly three-minute track ceiling both kick in.

Stable Audio's own credit system, separate from Suno's and Udio's, prices generations by output quality: a Draft-tier track costs 5 credits, a Studio-tier track 8, a Pro-tier track 10 and a Max-tier track 12, with roughly 100 credits per dollar spent, according to pricing trackers referencing Stability AI's documentation. That is the only platform in this shortlist where quality tier, not song length, is the main cost lever.

Suno vs Udio: the head-to-head most people are actually deciding

Most buyers in this category are choosing between exactly these two, so the comparison deserves its own answer rather than a shared table row.

Suno wins on portability. An $8-a-month Pro subscription gets you 20 downloadable, commercially licensed songs a month, generated from v6 or v6-wild, editable section by section without regenerating the whole track. That editing granularity is new with v6. Earlier Suno models forced a full regeneration for even a one-line lyric change, which made iterating on a chorus expensive in credits.

Udio wins on catalog access, at a cost. Because Universal, Warner, Merlin and Kobalt have all licensed material into Udio's system, subscribers can remix and reference a wider range of production styles than Suno currently exposes, using tools the company calls Styles, Remix and Extend. The tradeoff is that everything stays inside Udio's own listening and sharing environment. You can build a full setlist there and never own a single file.

If your workflow ends with uploading an MP3 somewhere else, such as a video edit, a podcast host or a client delivery, Suno is the only one of the two that gets you there today. If your workflow is entirely inside Udio's own player, for personal listening or in-app sharing, the download restriction costs you nothing.

Who should skip AI song generators entirely

Three groups are better served elsewhere.

Anyone who needs a specific named artist's voice, cloned or impersonated, should stop here. Every platform in this category bans voice-likeness cloning of real performers in its terms of service, and the current wave of label licensing deals exists specifically to prevent that use case, not enable it.

Anyone who needs a sub-30-second, royalty-free loop for a video background is paying for more than they need. Simpler, cheaper background-music generators built for that exact job, such as Boomy, exist outside this shortlist and are usually priced closer to a one-time purchase than a $8-plus monthly subscription. A full song generator's editing and mashup tools, the parts of Suno and Udio's pricing you would actually be paying for, go unused for a single ambient bed.

Anyone assembling a live band arrangement needs sheet music and stems built for human musicians to read and play, which is a different deliverable than an AI-rendered master track. None of the three active platforms above are built to output that.

And anyone still comparing Riffusion's old free tier against Suno or Udio on price is comparing against a product that stopped existing. That comparison shows up often enough in older forum threads and roundups that it is worth stating plainly: there is no current Riffusion pricing to compare, because there is no current Riffusion.

The obvious objection: v6 launched one day before this was published

Day-one software launches are usually the wrong moment to recommend anything. Rollouts stagger, edge cases surface in the first week, and Suno itself has not published a per-account timetable for when every subscriber gets v6 access instead of the retiring v5.5.

That objection is fair. It does not change the pricing or download math above. Suno's Pro and Premier plans, their credit ceilings and their download caps are billing terms, not beta features, and Suno has said plainly that v6 replaces its entire model lineup rather than sitting alongside the old one. The safer read is that this shortlist's prices and rights will hold even if the exact output quality of v6 versus v6-wild takes a week or two to settle across every account.

Where this could flip: if Udio's licensed platform ships downloads before this guide is next refreshed, the pricing math above changes for anyone who has been generating inside Udio's walled garden since October 2025, sometimes for months, with nothing to export. It could also flip the other way. If Suno's Premier tier turns out to need more than 10,000 credits to reliably hit a usable v6 take, the effective cost per finished song rises even though the sticker price does not move.

Run any shortlist candidate through Smart Match if none of the three above map cleanly onto your workflow. It weighs the same tradeoffs against your specific volume and budget rather than a generic "best for" label, and it draws from the wider AI content-creation category hokai tracks beyond just these four tools.

Udio has said it wants to restore downloads once its licensed platform is complete. It has not said when. The day it does, every song generated inside Udio since October 29, 2025 either becomes exportable retroactively or it does not, and nobody outside Udio knows which yet.

Frequently asked questions

What is the best AI song generator in 2026?

Suno is the best overall pick if you need a finished, downloadable song, especially after its September 9, 2026 move to the label-licensed v6 model lineup. Udio is a strong alternative if you are comfortable composing and listening entirely inside its own platform, since its Universal Music Group deal disabled downloads in October 2025. Neither is universally best; the download question decides it for most buyers.

Can you still download songs from Udio?

No. Udio disabled downloading of audio, video and stems the moment its Universal Music Group partnership took effect on October 29, 2025, according to Udio's own help center. The company has said it wants to restore exports once its fully licensed platform launches, but has not given a date.

What happened to Riffusion?

Riffusion no longer operates as a standalone product. As of this publication, riffusion.com redirects through producer.ai to flowmusic.app, a different branded platform, with no Riffusion-specific page remaining anywhere in that chain.

How much does Suno cost after the v6 launch?

Suno's Pro plan is $8 a month ($6.40 billed annually) for 2,500 monthly credits and 20 downloads, with commercial use included. The Premier plan is $24 a month ($19.20 annually) for 10,000 credits and 60 downloads, plus access to Suno Studio. The free tier offers 50 daily credits but no downloads and no commercial rights.

Is there a good AI song generator without vocals?

Yes. Stable Audio, from Stability AI, is built for instrumental tracks rather than full songs with lyrics, with commercial rights included on its paid tier and generations capped around three minutes. It suits background music, short-form video and production beds better than Suno or Udio, both of which are built around vocal songs.
